Until now, I have taken special care of pages which Xen needs to write, for instance current->thread.esp0, and page tables mapping network buffers, as otherwise Xen will just kill my domain upon write fault. This is becoming a bit of a hassle, so I am wondering if it would be possible for Xen to simply forward page faults to the faulting domain (microkernel style) instead of killing it? I am probably going to try and implement this myself, unless someone can tell me why this is a horrible idea.
